The Wallform 375 system

1. The numerical code assigned to each product range indicates the thickness of the block in millimetres. 250, 313 (the standard system), 375, 438 – the Wallblock is 250, 313, 375 or 438 mm wide, including the concrete core.

2. The tongues on the top and grooves on the bottom of components are arranged to interlink and crosslink in a modular grid of 62.5mm.

3. The tongues and grooves have a positive interlock so that the elements cannot be carried away by a gust of wind.

4. The normal hollow core of the components is 140 mm, calculated to optimise economy of design and building processes. Thicker concrete cores are available in increments of 62.5 mm for more demanding structural design.

5. All faces have grooves 2.5mm deep and 17.5mm wide in a pattern repeated every 62.5mm to eliminate thermal bridging. These grooves have a dovetail profile to provide a mechanical key for the application of plaster.

6. Location detail for horizontal reinforcement.

7. End pieces are inserted above and below the bridges to make a closure when forming corners, reveals and wall ends.

8. The bridges are tapered at the top and bottom to avoid trapping air during concreting.

9. Steel bridges may replace the integral insulation bridge for particular performance specifications.

10. The firewall endpiece is used to form the closure where this does not coincide with the bridge or where the system specifies steel bridges.
